I'm glad to see that the Hopper can handle more than one EHD at a time, initial reports said no. I'm not glad to see that I might have the same issues that I have had with my 922 since day 1. Since the Hopper apparently was built on the same platform as the 922 I guess I shouldn't be too surprised. Occasionally my 922 does not see the two WD EHD's I have connected. A front panel reboot usually fixes the problem but it's a hassle waiting. One of the drives has WD Smartware the 2nd doesn't so turning off the power save feature (spin down) doesn't seem like it would make any difference, at least in my situation. I do have to say that it's much more stable now. Early on I would lose connection every 3-4 weeks. Now it's more like 3-4 months.
